A vulnerability in versions prior to `1.0.0.CR3-20260417.085727-30` impacts publicly accessible software depending on the affected versions of Network and allows an attacker to exploit a vulnerability in Network to stall the netty event loop, rendering it inoperable. All consumers of the library should upgrade to at least version `1.0.0.CR3-20260417.085727-30`. There are no known workarounds beyond updating the library."

Una vulnerabilidad en versiones anteriores a ’1.0.0.CR3-20260417.085727-30’ afecta al software de acceso público que depende de las versiones afectadas de Network y permite a un atacante explotar una vulnerabilidad en Network para detener el bucle de eventos de netty, dejándolo inoperable. Todos los consumidores de la biblioteca deberían actualizar a al menos la versión ’1.0.0.CR3-20260417.085727-30’. No se conocen soluciones alternativas más allá de actualizar la biblioteca."
